It is a parent’s worst nightmare. The grocery stores are empty. The pantry is getting low. And you are down to your last canister of baby formula.
In a moment of panic, the logic seems sound: “If I add twice as much water, the bottle will last twice as long.”
Stop.
In Chapter 6 of Survive From The Pantry, we discuss why this simple math can be fatal for an infant.
The Danger of “Stretching” Formula
You cannot treat baby formula like soup. It is a precise chemical balance.
Infants have developing kidneys that cannot handle excess water. When you dilute formula, you disturb the electrolyte balance in their tiny bodies.
This leads to Water Intoxication, which can cause seizures, brain damage, and even death—often faster than starvation would1.
Rule #1: Never add extra water to stretch a ration. It makes a baby sick fast2.
The Temperature Rule (70°C / 160°F)
When the grid is down, you don’t just worry about the powder; you worry about the water quality and hygiene.
If you are using powdered formula, the water needs to be boiled and then cooled, but not too cool.
The water must be at least 70°C (about 160°F) when you mix it3.
Why? This temperature is high enough to kill bacteria that might be lurking in the powder itself (like Cronobacter), but cool enough not to scald the baby instantly (though always check before feeding!).
What If Formula is Gone?
If you have absolutely zero formula left, what do you do?
Under 12 Months: Do NOT switch to cow’s milk if possible, as it lacks the right nutrients4.
Over 6 Months: You can supplement with “pantry purees.” Canned peaches (rinsed of syrup) or peas can be mashed with a fork5555. You can mix a spoon of dry oats into the mash to create a filling baby cereal6.
Hygiene Without Running Water
A dirty bottle is just as dangerous as bad water.
If you don’t have clean bottles, cup feeding (using a small cup or jar) is actually safer and easier to clean7. Always stir with a clean spoon, never your fingers8.

Do you know which foods are choking hazards? Do you have a chart for rehydration if your baby gets sick?
Don’t guess with a life. Follow the protocol.
